Abstract
In this paper, epoxy nanocomposites, focusing on the electrical properties of the composites to understand controllers, circuit breakers, bushings and power to apply to the modified instrument was carried out basic research. Composed of composites of this study to develop a power unit to control the dispersion synthesis technology is essential electrical appliances such as electrical properties analysis techniques will also need basic research skills and experience accumulated in this study, several areas of applied technology. In this study, promotion and application of nano-composite material application technology power devices than conventional insulation materials and excellent electrical properties and easy synthesis and high reliability are expected to be practical if you expect that its effects are very large. Therefore, this study has very importance.
